enable inlining; speed!

Browse source 
* module/system/il/inline.scm: New module, implements generic inlining of
  scheme functions. It even does the right thing regarding (define
  arity:nopt caddr) and such. So now there are many more inlines: the
  arithmetics, `apply', the caddr family, etc. This makes the benchmarks
  *much* faster.

* module/language/scheme/translate.scm (trans): Remove the
  %scheme-primitives code in favor of the generic (scheme il inline)
  code. Adds inlining for +, -, =, etc.

* src/vm.c (vm_puts): Fix to work.

* module/system/base/compile.scm (system): Export load/compile also.

* module/system/il/compile.scm (optimize): Further debitrotting, but I
  haven't tried this function yet. It seems that <ghil-inst> was what
  <ghil-inline> is.

* module/system/il/ghil.scm (*core-primitives*, *macro-module*)
  (ghil-primitive-macro?, ghil-macro-expander, ghil-primitive?): Remove
  these unused things.

* module/system/il/macros.scm: Removed, replaced with inline.scm.

* module/system/vm/assemble.scm (stack->bytes): Before, the final
  serialization code did an (apply u8vector (apply append (map
  u8vector->list ...))). Aside from the misspelling of append-map, this
  ends up pushing all elements of the u8vector on the stack -- assuredly
  not what you want. But besides even that, I think that pushing more
  than 32k arguments on the stack brings out some other bug that I think
  was hidden before, because now we actually use the `apply' VM
  instruction. Further testing is needed here, I think. Fixed the code to
  be more efficient, which fixes the manifestation of this particular
  bug: a failure to self-compile after inlining was enabled.

* module/system/vm/bootstrap.scm: New module, serves to bootstrap
  boot-9's `load-compiled'. That way when we load (system vm core), we're
  loading compiled code already.

* module/system/vm/core.scm: Use (system vm bootstrap).

* src/guilec.in: Use the bootstrap code, so that we really are compiling
  with an entirely compiled compiler.

* module/system/repl/repl.scm (default-catch-handler): An attempt at
  making the repl print a backtrace; more work needed here.

* module/system/vm/frame.scm (make-frame-chain): Fix some misspellings --
  I think, anyway.
